You've built something real. But when a buyer looks at your plumbing business, they're not looking at it the way you do. They're running a checklist — and if you don't know what's on that checklist, you'll either leave money on the table or lose the deal entirely.
Here's what actually matters to the three main buyer types in today's market.
The Three Main Buyer Types
Not all buyers want the same thing. Understanding who's likely to buy your business shapes how you position it — and what you prioritize in the years before you sell.
| Buyer Type | What They're Buying | What They Pay | What Kills It |
|---|---|---|---|
| Private Equity / Platform | Scalable EBITDA, recurring revenue, owner-independent ops | 4–6x EBITDA | Owner dependency, no service agreements, messy books |
| Strategic / Competitor | Customer base, geography, crews, licenses | 3–5x EBITDA | Customer concentration, overlapping service area |
| Search Fund / Individual | Stable cash flow, owner willing to train | 2.5–4x SDE | Too complex to operate, no real processes |
The 8 Things Every Serious Buyer Evaluates
1. Revenue Recurrence
Is your revenue predictable? Buyers — especially PE — want to underwrite what next year looks like before they close. Service agreements, maintenance contracts, and commercial retainers are gold. Pure break-fix is not.
If 60%+ of your revenue is recurring or semi-recurring, buyers will pay more and close faster. If it's all call-in work, expect scrutiny and haircuts on your multiple.
2. Owner Independence
This is the single biggest deal-killer for businesses under $3M EBITDA. If you answer every service call question, handle all the hiring, and maintain the key customer relationships personally — buyers see that as a liability, not an asset.
They're not just buying revenue. They're buying a business that still runs after you leave. Document your ops. Promote a strong service manager. Build systems before you go to market.
3. Financial Cleanliness
Buyers will ask for 3 years of P&Ls, a trailing twelve month (TTM) view, and your most recent tax returns. If your financials are messy — personal expenses run through the business, revenue recognized inconsistently, large unexplained variances — expect buyers to discount or walk.
A clean set of books with normalized EBITDA (add-backs clearly documented) signals a sophisticated seller and reduces perceived risk. Hire a fractional CFO or at minimum get a CPA who understands buy-side due diligence.
4. Customer Concentration
If one customer represents more than 15–20% of your revenue, most buyers flag that as a risk. If they leave after close, the business is worth significantly less than what was paid.
The fix: diversify before you sell. Or be ready to offer an earnout tied to that customer's retention.
5. License and Compliance Structure
Plumbing is licensed differently than HVAC. In many states, work requires a master plumber license — and that license often lives with the owner. If the buyer can't easily transfer or replicate that license, it creates a real transition risk.
Buyers will ask: Do you have licensed employees who could hold the qualifier license post-close? Can the license transfer smoothly? Budget 30–90 days for this process depending on your state.
6. Employee Retention Risk
Your crews are the business. If three journeymen plumbers leave after you announce a sale, revenue drops immediately. Buyers evaluate this hard.
Things that mitigate this risk: long-tenured employees, above-market pay and benefits, written employment agreements for key staff, and a credible story about why the business is better post-sale (not worse).
7. Growth Thesis
PE buyers need to tell their LPs a story about how they'll grow what they bought. That means they're looking for: adjacent geographies you haven't captured, commercial segments you could expand into, add-on acquisition targets in your market, and service lines you're not currently offering.
If you can point to a clear, credible growth path — and show you haven't already picked all the easy fruit — you're a better acquisition target.
8. Real EBITDA
Everything comes back to this. Buyers will normalize your financials, strip out add-backs they don't believe, and stress-test your margin. If your claimed EBITDA doesn't survive due diligence, the deal reprices — or dies.
Run your business like a public company for 24 months before you sell. That means paying yourself a market-rate salary (which buyers will add back), not running personal expenses through the business, and documenting every discretionary expense.
- Undisclosed customer concentration — buyer discovers one customer is 30% of revenue during due diligence
- License dependency on the owner — no clear plan for post-close licensing
- Recast EBITDA doesn't hold up — add-backs can't be verified or are questioned
- Key employee departures — announced too early before close, crews leave
- Environmental or liability issues — open lawsuits, OSHA violations, permit problems
How to Position Your Business for the Right Buyer
The highest-value exits happen when owners prepare intentionally — not reactively. That means starting 18–24 months before you go to market and systematically addressing the items above.

There's a Third Option PE Firms Won't Tell You About.
PE takes majority control and runs on their timeline. Strategic buyers often mean a culture shift. There's a different kind of partner: someone who takes a minority stake, brings Hook Agency's marketing firepower and personal investment, and helps you build the business buyers compete to acquire.
